HEC-RAS 7.0

The Hydrologic Engineering Center's (HEC) River Analysis System (HEC-RAS) software allows you to perform one-dimensional steady and 1D and 2D unsteady flow river hydraulics calculations.
HEC-ResSim 4.1

The Hydrologic Engineering Center's (HEC) Reservoir System Simulation (HEC-ResSim) software is used to model reservoir operations at one or more reservoirs for a variety of operational goals and constraints.
HEC-RTS 3.5

The Hydrologic Engineering Center's (HEC) Real Time Simulation (HEC-RTS) software is a comprehensive data acquisition and hydrologic modeling system for short-term decision support of water control operations in real time.
HEC-HMS 4.13
The Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed systems. The software includes many traditional hydrologic analysis procedures such as event infiltration, unit hydrographs, and hydrologic routing.
